Each year, Wildlife Conservation Society scientists publish more than 300 peer-reviewed studies and papers. “WCS 3-Sentence Science” is a regular tip-sheet — in bite sized helpings — of some of this published work.

Here we present Irfan Yulianto’s recent work on grouper fisheries:

1. Eight global positioning system (GPS) trackers, used in an artisanal grouper fishery in Indonesia, showed that spear-gun fishers tend to fish within a marine protected area (MPA) and hook and line fishers tend to fish in the southern (outside) part of the MPA.
2. This information could support the traceability of the catch, which is a mandatory requirement in the global market, while providing more accurate stock assessments.
3. Better information supports the spatial management of MPAs, and a surveillance officer could use this information to increase the awareness of the fishers to avoid entering the core zone of MPA during a fishing operation.
